> Basically, why is consciousness always attached to the same physical body?
Because conciousness (or rather, subjective perception) is a physical phenomenon after all - it's causally linked to the universe in a way that means it can't just "jump" brains absent some kind of telepathy.
Identity is not really mysterious from a "hard problem of conciousness" POV; it's simply one phenomenology (one 'quale') among many, and experienced meditators can even turn it on and off at will. It's really only proto-perception and perhaps proto-cognition that probably needs to be explained.
